I am using the Flash 2.0 Beta viewer with AGS 9.3 cached map services. When I use the map services with Flex Builder 3 and the REST 1.3 API, the displayed map looks fine with the antialiasing being displayed (attached image maps1_3viewer.png). However, when I display the same map service in the Flash Builder 4 Beta Viewer using the REST 2.0 API, the map is much more primitive looking (attached image maps2_0viewer.png). I created the caches as PNG24, DPI 96, anti-aliasing on. Am I missing a parameter or is this how it is until we installed ArcGIS 10 SP 1 (yes, clients choice to wait until SP1).
Thanks,
